Broadcom AEDR-9940-100 Three-Channel Reflective Incremental Encoder with Analog or Digital Differential Output

Product Description:
AEDR-9940-100 is a three-channel reflective optical encoder. Selectable and programmable options are available for three-channel digital or analog differential A, B, and I output. The AEDR-9940 digital encoder mode offers two-channel (AB) quadrature digital outputs and a third channel digital index outputs. Being TTL compatible, the outputs of the AEDR-9940 encoder can be interfaced with most of the signal processing circuitries.

Key Features:
Analog Output option – Three-channel single-ended and differential analog output and analog or digital index output.
Digital Output option – Three-channel differential or TTL compatible; two channel quadrature (AB) digital outputs for direction sensing and a third channel, index (I) digital output.
SPI programmable interpolator from 1X to 1024X.
Surface-mount leadless package – 4.0 mm (L) x 4.0 mm (W) x 0.7 mm (H).
Operating voltage of 3.3V and 5.0V supply.
Built-in LED current regulation.
Wide operating temperature range from –40°C to 115°C.
High encoding resolution: 198.4375 LPI (lines/inch) or 7.8125 LP mm (lines/mm) or 0.128 mm (pitch).
Translucent protection compound.
